* kernel.bbclass: Allow initramfs to be built from a separate multiconfigAlejandro Hernandez Samaniego2022-01-261-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There may be a case where we want to build an initramfs image that doesnt inherit the same DISTRO_FEATURES (or others) from the main image being built. For example we may want our initramfs not to inherit a certain conf or feature, say we want to use musl for a smaller footprint, but if we are using TCLIBC=glibc for our DISTRO (and inherently our main image), the initramfs image would inherit that conf and be forced to use glibc, growing in size as a side effect, currently avoiding this is not supported. Allow the kernel class to create a multiconfig dependency (mcdepends) vs depends for do_bundle_initramfs and define our INITRAMFS_IMAGE from a separate multiconfig via two new variables: INITRAMFS_MULTICONFIG and INITRAMFS_DEPLOY_DIR_IMAGE which define the multiconfig where the initramfs image should be coming from and its deploy directory respectively, these two keep a default definition which preserves current behavior (do_bundle_initramfs uses depends). Example usage: - Create and use multiconfig initramfscfg.conf and set TCLIBC=musl there, along with its TMPDIR. - Add the following to our DISTRO.conf: INITRAMFS_MULTICONFIG = "initramfscfg" and set INITRAMFS_DEPLOY_DIR_IMAGE to the DEPLOY_DIR_IMAGE of the initramfscfg multiconfig (hence our main kernel will be able to grab it from there and bundle it). This will result in our musl based initramfs bundled in our main kernel and our main image to be glibc based.

* kernel: improve transformation from KERNEL_IMAGETYPE_FOR_MAKEMike Crowe2021-12-091-3/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In 526bdd88ccd758204452579333ba188e29270bde the imageType loop in kernel_do_deploy was changed to use KERNEL_IMAGETYPE_FOR_MAKE rather than KERNEL_IMAGETYPES. This broke the special handling for fitImage immediately below because KERNEL_IMAGETYPE_FOR_MAKE never contains fitImage. It has always been my understanding that KERNEL_IMAGETYPE_FOR_MAKE controlled what was passed to make, but KERNEL_IMAGETYPE controlled what was installed/deployed. When the two are different then it's the responsibility of whoever set KERNEL_IMAGETYPE_FOR_MAKE to ensure that whatever comes out of the kernel build system has been transformed in to the requested form by the time of installation. This is what happens for kernel.bbclass's own support for vmlinux.gz. I think this means that for KERNEL_IMAGETYPE vmlinux.gz, kernel.bbclass is responsible for generating vmlinux.gz.initramfs[1] so that kernel_do_deploy can deploy it. This means that the change in 526bdd88ccd758204452579333ba188e29270bde can be reverted, fixing KERNEL_IMAGETYPE = "fitImage". In addition, it ought to be possible for recipes and other classes that use kernel.bbclass to hook into this mechanism by setting KERNEL_IMAGETYPE_FOR_MAKE and performing their own transformations. do_bundle_initramfs calls kernel_do_compile and we don't want it to transform vmlinux to vmlinux.gz at that point, since it will fight against the careful renaming and preserving that do_bundle_initramfs does. Let's separate the transformation out of kernel_do_compile to a new do_transform_kernel task that can be run at the right time. This means that it's also logical to perform the equivalent translation for the kernel with the initramfs in a separate do_transform_bundled_initramfs task too. This leaves two clear customisation points for recipes and other classes to hook into the process and perform their transformations: do_transform_kernel and do_transform_bundled_initramfs. (I care about this because our recipes that use kernel.bbclass also set KERNEL_IMAGETYPE_FOR_MAKE and transform vmlinux into a form suitable for our bootloader after do_compile and do_bundle_initramfs into the format matching KERNEL_IMAGETYPE. I'm unable to successfully bundle an initramfs after 526bdd88ccd758204452579333ba188e29270bde, but I didn't want to just revert that change to reintroduce the bug that it was fixing.) I can't say that I'm entirely happy with this change, but I'm unsure what to do to improve it. I find the way that both the bare kernel and the one with the initramfs both get deployed to be confusing, and a waste of build time. I would like to not actually generate a publishable kernel image at all during do_compile when an initramfs is in use, but I suspect that this would affect valid use cases that I'm not aware of.

* kernel: export native PKGCONFIG variablesBruce Ashfield2021-11-261-0/+7
| | | | | | | | | | | | | | | | | | | | | | In a similar manner to cml1.bbclass, we export the pkg-config variables to allow a direct call to pkg-config access to the native sysroot versus the target sysroot. The kernel doesn't use pkg-config for target configuration, and has many explicit calls to pkg-config, without the possibility of easy override to pkg-config-native. The calls to pkg-config could be made cross friendly via replacement with make variables, but until that effort is undertaken upstream, we need a bridge approach. In particular, this is required for dtschema validation, which is a requirement in kernel 5.16+ (From OE-Core rev: 9172d61c57e23682c3d2c25701cbd53c84d01a27) Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

Multiple kernel providers can be dealt with in the same way as any multiple provider.

The current runtime-dependency references (with only package names without full versions) allow mixed package installations from different rebuilds of the same kernel version. This creates an issue because then the modules either don't work or taint the kernel. Tighten RDEPENDS with the full package version, i.e. use (= ${EXTENDPKGV}) markers for inter-package dependencies. The kernel will pull in the kernel-modules subpackage of the same exact version automatically if KERNEL_SPLIT_MODULES="0" is set. Otherwise the situation is the same as with the old default with one subpackage per kernel module where they have to be upgraded manually.

* kernel: relocate copy of module.lds to module compilation taskBruce Ashfield2020-11-181-1/+4
| | | | | | | | | | | | | | | | | | | | There were two copies of this patch floating around, and the merged variant has the copy in the wrong place. module.lds is only created during modules_prepare, and that target is not invoked during our main build of the kernel. We aren't about to change the kernel build (there's no need), so we move the copy into the compile_kernelmodules task. After that runs, we have module.lds availble to copy. This has been tested against clean kernel + out of tree module builds, and the dependencies are correct that the file is copied before the out of tree module build starts.

* kernel: provide module.lds for out of tree builds in v5.10+Bruce Ashfield2020-11-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The upstream commit 596b0474d3d [kbuild: preprocess module linker script], adds a dependency on module.lds for external module building. Since module.lds is generated as part of 'modules_prepare', we must make it available with the other kernel artifacts in the kernel shared workdir, otherwise out of tree builds fail. This fixes errors like: | make[4]: *** No rule to make target 'scripts/module.lds', needed by 'build/tmp/work/qemuarm64-poky-linux/cryptodev-module/1.11-r0/git/cryptodev.ko'. Stop. | make[4]: *** Waiting for unfinished jobs.... We also ensure that kernel-devsrc has a copy to support on target module builds that are often prepared with 'make scripts prepare'. Those targets won't regenerate it, so the build fails. If 'make modules_prepare' is used, the file will be regenerated and overwrite our copy (as expected).

* kernel.bbclass: ensure symlink_kernsrc task gets run even with externalsrcRasmus Villemoes2020-09-281-1/+4
| | | | | | | | | | | | | | | | | | | | | Commit c5dfc2586b41 (kernel.bbclass: run do_symlink_kernsrc before do_patch) fixed a race between do_symlink_kernsrc and do_populate_lic. However, I missed the fact that when externalsrc.bbclass is in use, the do_patch task doesn't exist, meaning that do_symlink_kernsrc now doesn't get run at all, breaking the build. We need this task to run regardless of whether do_patch exists or not, so reinstate the configure->symlink_kernsrc dependency explicitly.

However, it will also end up changing PKGR differently then do_package as the BB_TASKHASH used will be for the wrong task. Generally this won't cause any real-world issue, but it could cause problems. Moving to read_subpackage_metadata ensures that the values used in do_package will be read in and used for kernel deployment.

| | | | | | | | | | | | | | | | | | | There's a race between do_symlink_kernsrc and do_populate_lic, since the latter is ordered "after do_patch"; so the two may run in parallel. In some cases, that actually causes do_populate_lic to fail if it happens to look for a license file somewhere under ${S} in the short window after shutil.move and before the symlink has been created. Fix that by simply ordering symlink_kernsrc before do_patch. Any task that pokes around in ${S} looking for files should be ordered after do_patch, so this should also fix similar latent races with other ad hoc tasks.

| | | | | | | | | | | | | | | | | | | | | | do_deploy should clean up ${DEPLOYDIR} before running, just like do_install cleans up ${D} before running. This reduces the risk of DEPLOYDIR being accidentally contaminated by files from previous runs, possibly even with different config, in case of incremental builds. It is convenient to have this in deploy.bbclass, so it doesn't have to be duplicated in every recipe, considering for example meta-freescale, which has 23 affected recipes. All recipes using deploy.bbclass (grep -r 'inherit .*deploy') in poky, meta-openembedded and meta-freescale look like they either benefit from this or are at least not affected negatively by it. The only exception I've noticed was uboot-sign.bbclass, which was however fixed by the previous patch.
